Gas Phase Kinetic Modeling and Sensitivity Analysis of B/H/O/C/F Combustion Systems

Abstract

A kinetic model is presented to describe the high temperature, gas phase B/H/O/C/F chemistry associated with fluoroamino/nitroamino/B(s) mixtures. The results of thermodynamic constant temperature and pressure calculations for a prototypical fluoroamino/nitroamino based oxidizer and solid boron are presented to characterize the equilibrium speciation under boron rich and boron lean conditions. Based on an analysis of the predicted equilibrium speciation, key gas phase reactants are selected and a reaction mechanism describing potential reaction pathways is formulated. Rate parameters for elementary reactions were obtained from published experimental/theoretical data or estimated using transition state arguments and scaling relations. The results of kinetic calculations for several isothermal and adiabatic systems are presented which illustrate the general high temperature mechanistic behavior of B/H/O/C/F systems. Standard reaction flux/pathway and gradient sensitivity analysis techniques are used to identify important reaction pathways.... Boron, Kinetic model, Sensitivity analysis, Combustion.
